U+10405 "𐐅" Deseret Capital Letter Long Oo Unicode Character

U+10405 "𐐅" Deseret Capital Letter Long Oo is a glyph from the Deseret alphabet, a phonetic script created in the mid-19th century by the Church of Jesus Christ of Latter-day Saints under Brigham Young as a reform to simplify English spelling. This specific character represents the long vowel sound typically denoted by the digraph "oo" in words like "boot" or "moon". Despite failing to gain widespread adoption, the Deseret alphabet was used in a few printed works and is now preserved as a historical and cultural artifact in the Unicode standard, with this capitalized form serving as the uppercase version of the letter.
